I just got one in the coyote finish. I've been playing with it in the dark for a few hours and like it. It is similar in size to a 100mm cigarette (see the photo). It charges using a USB port. It comes with a 5" USB cable that plugs into a port that is exposed when the cap is slid forward. It has two power modes; a 250 Lumen and a 50 Lumen. I like the low power for walking around in a dark room. The bright beam works well for me when I walk outside in the dark illuminating where I'll be walking. It fits unobtrusively in my pocket along with other EDC pocket stuff. Price seems to be about $30 from most suppliers.
